"The Newbie-2015. Winter" tournament.

2 fall from the top and 4 pass from the bottom, totaling 6 players and 3 games, isn't that right?

Usually, it's not like that; the rounds in the lower bracket alternate – a round between players in the lower bracket, followed by a round of players from the lower bracket against those who fell from the upper bracket.
Therefore, in the 3rd round of the lower bracket, the following should play:
1) Noom-Loinz / Chocolate Puma - MoxuTo
2) Jubi-Juby - Telder54 / MikeM
And in the 1/4 of the lower bracket, the following should play:
3) winner of pair 1 - loser of Faria/Yar
4) winner of pair 2 - loser of Makiavelli/Socrat
Next, in the 1/2 of the lower bracket, the following play:
5) winner of pair 3 - winner of pair 4
Finally, in the final of the lower bracket, the following play:
6) Winner of pair 5 - against the loser in the final of the upper bracket.
